I think you hit the nail on the head. There likely isn't anything you're going to say that will really get through to your H. I think the best any LBS can do is try to take the high road on everything, don't get drawn into any arguments, do the best for the kids at all times and take care of yourself. If your H wakes up out of his craziness someday that would be awesome but from what I've read that can take a LONG time.
